Gurghiu - "Antique" grey andesite cobblestone 10 x 10 x 10 cm

The name andesite is derived from the Andes mountain range in South America. Being one of the most frequent igneous rocks in the Carpathian Basin, it is formed by the solidification of the magma rising to the surface. It can appear both as single and coherent blocks of stone, or foliated from horizontal to slant layers. The andesite has varied nuances: brownish grey, light and dark grey, blue-lilac, black. The andesite paver is frost and abrasion-resistant, non-skidding with high carrying capacity, that is why it is an important building and decorating stone. Due to these important physical properties its usefulness has been known for centuries, and it is widely used nowadays, too. As exterior stone veneer it is indispensible ornamental component of plinths, stonewalls, columns, balconies, stairs, walkways, at the same time being a popular natural indoor paver for wall cladding, too. The andesite can be acquired in irregular (raw) or cut-to-size slabs, its blast resistance makes it widely used as carved cobblestone, which is an important and quality veneer for drive- and walkways.Gurghiu - "Antique" grey andesite cobblestone: Thousands of years ago humanity realized the importance and benefits of using solid rocks for construction purposes, as quality stone pavers. Day by day we see newly emerged road-sections paved decades ago, which were long forgotten, but whose importance and quality are being recognized by more and more people. The andesite carved cobbles and curbstones are widely used, due to their blast resistance. Its colour varies from ash to dark grey. It has pyroxene in its structure, which is one of the andesite forming minerals. This mineral can appear in columns or in prisms, in this it is black, greenish or brownish. These minerals can be easily observed from close in this type of andesite. The andesite cobbles and curbstones are non-skidding with high carrying capacity, that is why it is an important quality paver for drive- and walkways, public squares. Its processing is done by carving in different sizes:Andesite cobblestone:
